IMPROVEMENT IN SPRING-HINGES.

Specification forming part of Letters Patent No 162,735, dated May 4,18:5 application inea October 2l, 1874.'

To all whom it may concer-n:

Be it known that I, JOSEPH ANNIN, of the city of Brooklyn, in the countyof Kings and State of New York, have invented an Improvement inSpring-Hinges, of which the followin g is a specification:

My invention consists in the application of a llat coiled spring to asleeve, and of so applying said sleeve and spring to a hinge that thesleeve and spring may be readily attached or detached for repairs, or'convenience inV manufacturing it, my object being to make a neatconvenient spring-hinge, so constructed that the spring may be taken outand repaired, or a new one pnt in its place, without removing the leafof the hinge from the door, and so that the parts may he made andshipped separatel y, and may be put together by any person-as, forinstance, if a spring gets weak, the party desiring to have it repairedhas only to send to the factory, giving size of hinge, and a spring andsleeve can he sent to him, and he can readily pnt it in place by takingout a screw, slipping the old sleeve and spring off, and putting the newone in its place. My construction also gi ves me a hinge with a loose orfast joint.

My invention will be more readily understood by reference to theaccompanying drawings, which form a part of this specification.

Figure l is a back view of the open hinge. Fig. 2 is an endview of myhinge, partly closed. Figs. 3, 4, 5, 6, and 7 are views of the partsseparate from each other.

A is the spring. B is the sleeve; C and D, the leaves 5 E, the spindle,that holds the parts together. F is a screw, that fastens the spring Ato the leaf D of the hinge. Gr is a pin, which holds the tension of thespring A by being inserted in one of the holes H, and rests against theleaf O of the hinge.

rIhe tension of the spring may be made greater or less by changing thepin G to different holes H. A ratchet and pawl might he used in place ofthe pin G and holes H.

A countersink or groove, I, is made in the leaf G, to receive the pin Grand hold it in its place.

To remove the spring and sleeve, draw the spindle E, the screw F, andpin G, and the sleeve and spring may be slipped out, and a new oneslipped in its place.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

The movable sleeve B, having` holes H, and provided with the spring A,attached in coinbination with the leaves G and D and pin G, allconstructed and operating as and for the purpose set forth.

JOSEPH ANNIN.
